摘      要：We have discovered a strong increase in the intensity of the chemiluminescence of a luminol flow and a dramatic modification of its spectral shape in the presence of metallic *** observed that pumping gold and silver nanoparticles into a microfluidic device fabricated in polydimethylsiloxane prolongs the glow time of *** have demonstrated that the intensity of chemiluminescence in the presence of nanospheres depends on the position along the microfluidic serpentine *** show that the enhancement factors can be controlled by the nanoparticle size and ***,the emission peak of luminol overlaps with the absorption band of the nanospheres,which maximizes the effect of confined plasmons on the optical density of states in the vicinity of the luminol emission *** observations,interpreted in terms of the Purcell effect mediated by nano-plasmons,form an essential step toward the development of microfluidic chips with gain *** implementation of the discovered effect will include improving the detection limits of chemiluminescence for forensic science,research in biology and chemistry,and a number of commercial applications.
